- Specifically'described, the glare; shield of. I the present invention'comprises a track 1'1 adapted to be mountedbyme'ans of a pair of brackets 12 and 13 in the forward portionf of a' closed automobile body: 14, "preferably just inside and adjacent the upper edge'of the windshield 16 thereof. The track 11 is preferably a strip of suitable metal, and in chides a straight portion 17 extending transversely of the'vehic le substantiallyparallel with the upper edge of the windshield 16, 1

and a curved portion 18 at onej end of the straight portion 17, itbeing understood that the bracket13 whereby the curved portion 18 of thetrack 11 is secured to the-body 14, 10o

is fastened to one of the side walls 19, whereas the bracket 12 is secured to the front wall '21. The provision of the curved portion 18 at one end of the track 11 permits positioning the glareshieldbetween the eyes of the operator of the vehicle and a source of light at one side of the vehicle, by sliding the glare; shield onto the curved. portion 18, whereas theeyes of the driver may be protected from light emanating from a source in front of the vehicle by sliding the glare shield onto the proper section of the straight portion 17, as Will readily be understood;

A head 26 is slidably mounted upon the track 11. This he'ad comprises a pairof 'opposed. shoes 27 and [28 ,having registering grooves 29 and 31,.respectively, in' their proximal fa'ces,these grooves extending. longitudinallyof theishoes. The track 11 ex- 'dftends through the groove .31 .of the shoe 28,

andlone face of ,thefltrack frictionally engages .thebottom ofithatgroove, as clearly shown upon Figs} 4 and 5. The opposite face of thejtrack 11 is engaged by a slipper 32,;the"bodylportion '33 of which also lies within the groove 31 of the shoe 28. This slipper 32 is pressed'toward and into engagement witllthe track 11 by preferably a pair of coil springs 34 under compression between theslipper 32 and the bottom of the groove 29 of-the other ishoe27.

The outer faces 36 of the'shoes 27 and 28 are arcuate about common axis which extends-longit'udin'ally" thereof, i. e., in paralilelism with the,;tr'ackj 11, and a housing 37;

of circular cross sectional configuration is mounted for; rotational adjustment upon the V outer surface 36 of the shoes. Preferably the housing 37 isformed from a flat strip of fmetal bent tocircular configuratiomzwith flanges 38 extending radially outwards at the joined edges of; the circular portion. Screws 39 andjnuts "41 releasably clamp the flanges 38'together, but permit separation V 37 holds the shoes-27 and 28 against separa tion,;'l the .result, being that the action'of v: springs 34'is to press the slipper 32 against with respect to the trackll, and also r0- of the flanges for ,thepurpose of assembly and disassembly of the head 26. The housing its associated face of the track 11, and also topres'sithe shoe T27" outwards against the housing37r This causes thehousing 37. to be pressed Vjwith equaljforce against the outer "surface of the other shoe 28, pressing the shoe 28'against the opposite face of thetrack 11 frointhat which is engaged by the slip per 32. V 5.

.Thus it may be seen that the springs 34 serve the dualfunction of resisting longitudinaljsliding movement of the head 26 tational movement of the housing 37 about the shoes 27 and. 28.

; Means are provided foridrawing the slippfi %.t wa d thes e ag n t the o ciatedend of the shoe 27 and in the outer surfac e'of that shoe. In order to retain each of the levers 44 in operative position, an aperture 48'extends through the shoe 27 from end 46 0f each lever 44 is defiectedtasindicated at 49, and seats within the associated aperture 48, as clearly shown upon Fig. 4. Hence, the inner end 46. of each lever 44 is track 11, the levers 44 which are in engage ment with the ears 42, will draw the slipper 32 outwardsfrom thetrack. When such a condition obtains, the, entireforce of the springs 34-will be neutralized by the-shoe 27, 1 theslipper 32 and the levers 44preventing any portion of .the force exertedjby the springs from pressing the'slipper 32 against the track, or the shoes 27 and 28 against the housing 37 the result being that the head 26 may then easily be slid longitudinally of the track, or the housing 37 may be rotationally adjusted about the shoes 27 and28 and track 11. I v

' fulcrumed upon an outer surface of the shoe I 27,, so that Whenthe outeri. ends. 5 1 l of the levers 44 are pulled outwards awayfroln the In order to facilitatemanipulation of the.

levers 44, the outer'ends 51 have been deflect.- ed into perpendicularity with the body portions of thelevers 44, and substantially into parallelism with each other, and inasmuchas the end 51 of each of thelevers 44 is ex posedexteriorly'of the housing 37, as clearly shown in Figs. 3, 4 and 5, they mayeas'ily be grasped between the thumb" and forefinger ofon'e hand and thus squeezed .toward eachj' other, causing the levers .to; fulcrum abouttheir 'inner ends andthuscompress the,

springs34 by dra i g e l pper 32.1towa11d the shoe'l27l. Preferably, abeadj 52-is formed on the body portion 33 ofstheslipper 32 inas celluloid. A"str ip.57, preferably ofj fifl la' 37 provide a convenient means for mounting is anchored to the flanges 38- by theiscrews f and nuts.39 and 41, respectivly, wherebythe flanges 38 are clamped together, and. the screen 56; fastened to the. otherendof the 80 each notch 47 tothegroove29, and the inner strip 57 by screws 58 and nuts 59 and a clampin strip 61.

lgs. 9 to 14 inclusive illustrate a modified form of glare shieldsupporting structure,

4 68 within which a pair of opposed shoes 69- and 71 are disposed, theseshoes being preferably of construction identical with the corresponding elements of the previously described modification, each being provided with a groove 72, 73, respectively, in that face thereof which is proximal to the other shoe, and these grooves 72 and 73 being in.

registry with each other, as clearly shown upon Fig. 10. The track 66 extends through the groove 73 of the shoe 71, and slidably' engages the bottom of the groove. A slipper 74 is in engagement with the other side of the 1 track 66 and is pressed thereagainst by means of preferablya single coilspring 76.

i This slipper 74 differs from the slipper 32' of the previously described -modification in that it is provided with preferably a pair of opposed ears 77 adjacenteach end thereof, these ears extending upwards from the plane of the body of the slipper 74 and along the side edges thereof. A notch 78 is formed 'in the inner edge of each ear 77. The operating levers 79 comprise handle portions 81' which extend through the ends of the housing 68 and are deflected into substantial parallelism, so that they may be squeezed together by grasping them between the thumb and forefingerof one hand. The inner ends 82 of the levers are deflected toward each other and then outwards again away from the track 66, as indicated at 83, these deflected portions, however, curving gradually into overlapping relationship, as clearly shown upon Fig. 11. Shoulders 84 are formed upon I the side edges of each of the levers 79, these shoulders being engageable within the notches 7 Sci the associated ears 77 with the portions 86 of the levers of reduced width extending between the ears, the'result being that the levers 79 are fulcrumed upon the sli per 74.

he spring 76 is under compression between the body portion of the slipper 74 and the overlapped ends 82 of the levers 79. Hence, the spring 76 continually urges the slipper 74 against the track and also presses the overlapped ends of the levers outwards so that one of these ends presses against the bottom of the groove 72 of the shoe 69,'and thereby presses the track 66 from thatwhich is engaged by the slipper 74.

Then the handle portions 81 of the lovers 79 are pressed together thexlevers fulcrum about their shoulders 84, pressing their overlapped ends .83 inwards against the action of the spring 76 and tending to pull the ears 77 p of the slipper 74 outwards. Hence the en-- tire quantity of force exerted by the spring 76 is neutralized by the slipper and the levers, the result being that the pressure of the slipper against the track, and also the pres- 7'5 sureof the shoes against the housing, are relieved, permitting facile adjustment of the i entire head 67 longitudinally of the track 66, and also permitting rotationof the housing. 68about the shoes.

This last mentioned adjustment,'which is facilitated by compression of the spring 76,

makes it possible to swing the glare shield 86 whichis'carried by an arm 87 secured to the housing '68, about a horizontal axis extending transversely of theautomobile, so that the shield 86' may optionally be placed in operative position before the eyes of the driver, or swung upwards against the top of the car out of the way. However, I have also provided means for varying the elevation of the shield 86 when the'arm 87 isextending' downwards from the track'66.

For this purpose," the arm 87 consists of two portions, a strip 91 which is rigid with the housing 68, and a preferably tubular portion 92 into which the strip 91 extends. A housing 93 is formed on one side. of the tubular portion 92,- and a slipper 94 inside the housing 93 engages the strip 91, which in this instance corresponds to the track of the previously described modifications. pressed against the strip or track, 91 by a spring96 which'is under compression between the slipper and the inner, overlapping ends 97 of levers 98 which are fulcrumed upon the ends of the slipper 94 through the expedient of ears 99 formed upon the ends ofthe slipper and seated within notcheslOl in the levers 98. Although this friction gripping deviceis not provided with acylindrical housing encircling a pair of opposed shoes, for the reason that it is not desired .to'attain adjustment about an axisparallel to or coinciding with that ofthe strip 91,'this, device is adjustable to permit movement thereof longitudinally of the track 91. This is attained by'squeezing the outer portions of the levers-98'together, which will increase-the compression of the spring 96 between the-inner ends ofzthe levers and. the slipper, thereby relieving the; pressure of the slipper against the track 91 and permitting easy adjustment of the tubular. portion 92 ofthe arm 87 with respect to the portion 91. The screen or shield 86, which The slipper '94 is preferably is of colored, transparent mate rial,"is fastened to the lower end of the tubu lar portion 92 by means of ascrew 10-2'having a n'utl03 thereon, so that when the last de5 scribedmodification of friction gripping decomprising a housing encircling said'track, a pair of opposed shoes disposed wlthin sald housing with said track extending between v 1 between the other of said shoes and said slip- Vice is adjusted upon the strip or'track 91, the shield is moved therewith. It is to be understood that the details of the invention as herein disclosed, are subject to alteration within the spirit or scope oftheappendedclaims.
